You're confusing chaotic systems with random systems. Chaotic systems are still deterministic. [1]

Newton thought that because he didn't know perturbation theory. Perturbation theory doesn't change the laws, it reformulates them as "simple thing + small tweaks + more complicated even smaller tweaks + ...". This allows you to quantify how stable the solar system is.
